Fees & payment
Stanislaus Health Services Agency in Modesto tests for gonorrhea, chlamydia, syphilis, herpes, hepatitis B, hepatitis C, and HIV, bacterial infections treated the same visit, with fees on a sliding scale and no appointment required.
Stanislaus Health Services Agency delivers testing, counseling, and STI treatment in Cambodian/Khmer and Spanish. Not through an auxiliary line but as part of the clinical encounter itself. For someone navigating a gonorrhea diagnosis or a hepatitis B result in a second language, that means the conversation about treatment adherence and partner notification happens without anything lost between speaker and provider.
Skipping herpes or hepatitis C from a panel means a separate appointment elsewhere, another scheduling delay before any treatment decision can be made. At Stanislaus Health Services Agency, the panel extends beyond gonorrhea, chlamydia, syphilis, and HIV to include herpes, hepatitis B, hepatitis C, and TB, closing those gaps in a single visit.

Golden Valley Health Centers, a community health center in Modesto, folds STI testing into primary-care infrastructure: meaning gonorrhea, chlamydia, syphilis, and HIV are handled alongside same-visit bacterial treatment, sliding-scale fees, and appointment-based scheduling, with care available in Spanish.
Golden Valley Health Centers staffs clinicians and support personnel who conduct visits, document histories, and explain treatment plans in Spanish directly. Not through an add-on service. Prescriptions are discussed, follow-up is scheduled, and test results are reviewed in Spanish as the working language of the encounter.
Substance-use treatment at Golden Valley is a clinical program operating within the same health center, so a provider managing an STI case can coordinate directly with the addiction medicine side: shared records, coordinated prescribing, and unified follow-up rather than two separate intake processes.
Beyond gonorrhea, chlamydia, syphilis, and HIV, Golden Valley runs herpes and hepatitis C testing on-site: hepatitis C through antibody screening with clinical follow-up, and herpes via serological testing ordered and interpreted by the same provider managing the rest of the panel.

STD stats & rates
How reported STI rates in Stanislaus County, the county that includes Airport, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~40% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#22 of 58 California counties for chlamydia, a higher rate than 62% of the state
| Infection | Stanislaus County | California | United States |
|---|---|---|---|
| Chlamydia | 399.3 2,202 cases ▼ 19% | 491.1 | 492.2 |
| Gonorrhea | 106.6 588 cases ▼ 44% | 190.2 | 179.5 |
| Syphilis (P&S) | 24.5 135 cases ▲ 50% | 16.3 | 15.8 |
| Syphilis (early) | 15.1 83 cases ▼ 21% | 19.1 | 16 |

Reading these numbers: reported case rates only count infections that were actually tested for and diagnosed, so they track local screening effort as much as true spread: a higher rate can reflect more testing, a lower one less. Either way, most STIs cause no symptoms, so treat the figures above as context rather than a verdict, and test on the CDC's schedule regardless of how your area looks.
Between 2020 and 2023 in Stanislaus County, chlamydia has fallen from 461.4 to 399.3 per 100,000 (13%), gonorrhea has fallen from 229.5 to 106.6 per 100,000 (54%), and P&S syphilis has fallen from 26.9 to 24.5 per 100,000 (9%).

Community health context
Sources: CDC PLACES (ZIP), County Health Rankings, CDC/ATSDR SVI, HRSA HPSA, HRSA MUA/P, Neighborhood Atlas ADI. Lower insurance coverage, fewer routine checkups, and a thin primary-care ratio all raise the value of low-cost public clinics and at-home testing in Stanislaus County.
Local HIV snapshot
Stanislaus County HIV care continuum (2023)
Stanislaus County recorded 12.2 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Stanislaus County residents living with HIV, 77.9% are in care · 70.8% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.
Sources: AIDSVu (Emory/Gilead) · CDC AHEAD · CDC AtlasPlus · CDC NCHHSTP AtlasPlus (county care continuum). The CDC recommends everyone aged 13–64 test for HIV at least once: every lab and clinic listed above offers HIV testing, and free rapid HIV testing is available at a local health department.
Congenital syphilis, passed from parent to baby in pregnancy, is the fastest-rising STI in the country. U.S. cases climbed from 2,163 in 2020 to 3,882 in 2023. It is almost entirely preventable: the CDC recommends a syphilis test at the first prenatal visit, and every clinic and lab listed for Stanislaus County tests for syphilis.

Two things that actually depend on California law: who can consent, and whether partners can be treated without their own visit. Everything else about testing privately is the same nationwide (see below).
In California, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
California permits Expedited Partner Therapy (EPT): if you test positive for chlamydia or gonorrhea, your provider can give you medication (or a prescription) to pass to your partner, no separate exam or appointment needed for them.
Keeping a test private works the same in every state. Whether an STD test shows on insurance (the EOB), how to test anonymously, and self-pay options that leave no insurance trail don’t change by location.
